What Happens to Passwords After QDay?

[GameChanger]

Q: Will quantum computers instantly crack every password? A: No, passwords are not the same thing as public key encryption, and a strong password hash still matters. Q: So where is the danger? A: Weak passwords, stolen databases, old hashing methods, and encrypted backups could all become more attractive targets as computing power improves. Q: What should users and site owners do now? A: Use long unique passwords, password managers, multi-factor authentication, modern password hashing, and remove old stored secrets that no longer need to exist.

This is a great myth-busting topic because a lot of people mix up passwords, encryption, and signatures.

The boring advice still wins here. Unique passwords and a manager solve more real problems than quantum panic does.

Old databases are the scary part. Sites that keep ancient hashes around are building future trouble for themselves.

I would add that deleting old data is underrated. You cannot leak a password reset table or backup that no longer exists.
